Entanglement recovery by reversing the effect of noise in quantum repeater

Sewon Jeong, Shrobona Bagchi, Jaehak Lee +4

We propose a method to directly recover the degree of entanglement distributed by entanglement swapping in the presence of noise. Our approach introduces a reversing operation that…

Interactions of pre- and postselected quantum particles

Gregory Reznik, Jan Dziewior, Shrobona Bagchi +1

An approach for analysis of effective interaction between pre- and postselected quantum particles is developed. It is argued that the cases of complete pre- and postselection of pa…

Concurrence speed limit and its connection with bounds in many body physics

Shrobona Bagchi

Quantum speed limit is a fundamental speed limit for the evolution of quantum states. It is the single-most important interpretation of the time energy uncertainty relation. Recent…

Stronger Quantum Speed Limit For Mixed Quantum States

Shrobona Bagchi, Dimpi Thakuria, Arun Kumar Pati

We derive a quantum speed limit for mixed quantum states using the stronger uncertainty relation for mixed quantum states and unitary evolution. We also show that this bound can be…
